[FFmpeg-user] Concatenation of 50-100 files

[Dzung Nguyen]

You're right, it's the concat demuxer. So I guess concat protocol ( or
simply cat of files) would be more robust? I read that mpg files is
cattable, but after cat files the final video has no time information
(unseekable, can't play).

This is how I create the subvideo:

ffmpeg -loop 1 -f image2 -i image.png -q:v 0 out1.mpg
